Google has a policy of encouraging the establishment of cache servers, mainly within bigger ISPs carrying volumes of traffic. In areas where there is higher traffic, Google sets up Points of Presence (PoP).

Google has also been working closely with SeaCom, one of the fiber optic cable providers, to host some of the servers and allow providers to exchange content at a neutral point.

"SeaCom has an open policy, we work with all providers to encourage content exchange," said Willem Marais, head of sales, Southern and West Africa for SeaCom. "We are hoping to bring in other content providers, which will lead to growth."

For the last four years, Google has been leading the drive to develop more African online content through app contests, university interconnection program and the digitization of government data.

"At the Nigeria IXP, we have a Google cache server and four universities are peering in order to interconnect to the Google program, which has driven up the content at the exchange," said Yen Choi, a board member at NIXP.
